AEB 07 Euro NCAP Summary Overview Euro NCAP
AEB 07 – Euro NCAP Summary Overview • Euro NCAP is a private consumer test organization, based in Leuven, Belgium, partly funded by European governments • Euro NCAP was established in 1997 • Euro NCAP tests apply to (passenger car) vehicles with standard equipment across EU-28 • Euro NCAP tests are optional, one does not need to have a valid star rating to be able to sell a vehicle in Europe • Euro NCAP stars are intended to be consumer information, there is no other implication from the test results

AEB 07 – Euro NCAP Summary AEB Vehicle-to-Vehicle • AEB V 2 V is part of the rating since 2014 • Scoring is based on collision speed • AEB City: - Adult Occupant Protection Box (4/38 points) (max. speed tested 50 km/h) - Automatic Intervention - stationary target only • AEB Interurban: - Safety Assist Box (3/13 points) (max. speed tested 80 km/h) - Forward Collision Warning followed by Dynamic Brake Support and/or Automatic Intervention - stationary, moving and braking target • Rating of FCW/DBS is based also on collision speed (pre-configured brake robot triggered by FCW)
AEB 07 – Euro NCAP Summary AEB City Test Scenarios Total 45 AEB City tests: • • Stationary target vehicle (GVT) 9 different ego speeds (10 km/h – 50 km/h in steps of 5 km/h) 5 different variants of lateral overlap (50% left - 75% left - 100% - 75% right - 50% right) Score is dependent on impact speed. OEM hands in a prediction “grid” (based on own tests, simulation, etc. ), no participation of Euro NCAP in prediction Euro NCAP will perform sample tests to verify the results, a correction factor could apply Total score: 4 points v 0 50 45 40 VUT Test Speed • • • 35 30 25 20 15 10 Full score (4 points): • No collision at 10 – 20 km/h • max. 5 km/h impact speed at 25 – 50 km/h Overlap GRID example: 50% L 75% L 100% 75% R 50% R
AEB 07 – Euro NCAP Summary AEB Interurban Test Scenarios Stationary target vehicle (CCRs) Ego: 30 – 80 km/h Test of FCW/DBS only (braking robot) (30 -80 km/h) Slower target vehicle (CCRm) Ego: 30 – 80 km/h Target: 20 km/h Test of Automatic Intervention (30 -80 km/h) and/or FCW/DBS (braking robot) (50 -80 km/h) Braking target vehicle (CCRb) Distance: 12/40 m Ego: 50 km/h, Target: -2/-6 m/s² Test of Automatic Intervention and/or FCW/DBS (braking robot) Grid approach - as in AEB City - variation of overlap value for CCRs and CCRm test - No grid applied for CCRb test (100% overlap only) For full score (3 points, combination of Automatic Intervention (1. 5), FCW/DBS (1. 0) and HMI (0. 5)): • max. 5 km/h (relative) impact speed allowed across the complete speed range

AEB 07 – Euro NCAP Summary Outlook 2020/2022 • Euro NCAP plans to • allow automatic emergency steering (AES) as an alternative to braking for applicable AEB scenarios from 2020 • include intersection and crossing scenarios for AEB V 2 V and V 2 P starting from 2020 • include Reverse AEB V 2 P starting from 2020 • update AEB existing V 2 B requirements in 2020 • include PTW as target for AEB VRU from 2022 • include an AEB Head-On function from 2022 • From 2020 AEB is an (implicit) requirement for five stars in Euro NCAP Four stars are (theoretically) still possible w/o AEB
AEB 07 – Euro NCAP Summary • Euro NCAP tests are optional, one does not need to have a valid star rating to be able to sell a vehicle in Europe • Euro NCAP stars are intended to be consumer information, there is no other implication from the test results • until today (2018) AEB is no prerequisite for a five star rating • some AEB tests are sample tests only • in some cases it is possible to repeat a failed AEB test, or repeat a test where the result deviates from the prediction of the OEM • full collision avoidance across the complete defined speed range is not required for a full score in any AEB test scenario
